Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery module and an energy storage device. Background Technology

[0002] In the product structure design of energy storage devices such as portable power supplies, the battery module is a core energy storage component, and its structure is usually tightly coupled with the overall product casing design. Each new model or product requires the design of a matching battery module. Designers need to specifically design suitable battery module structural components based on the internal space of the new model's casing, the component stacking layout, and the installation position of the fixing structure. These battery module structural components typically include dedicated upper and lower brackets, connecting aluminum busbars, and other parts. These structural components need to be manufactured using individual molds and then assembled into a dedicated battery module compatible with that specific model.

[0003] However, developing a new model or product of energy storage equipment requires creating new molds for the corresponding battery module structural components (such as the upper and lower supports in the battery module), which leads to a significant increase in research and development and production costs.

[0004] Therefore, designing a battery module that can be used by multiple different types of energy storage devices has become an urgent technical problem to be solved. Summary of the Invention

[0005] This application aims to at least solve the problem in the related technology that the battery module cannot simultaneously meet the needs of different models with different casings. The design of a new energy storage power supply for each new model requires the design of a matching battery module, which increases the number of molds to be developed for the structural components of the battery module and thus increases costs.

[0006] Therefore, the first aspect of this application provides a battery module.

[0007] A second aspect of the present invention provides an energy storage device.

[0008] In view of this, the first aspect of this application proposes a battery module for installation in at least two different mounting postures on various types of energy storage devices. The mounting postures include a vertical mounting posture and a horizontal mounting posture. The battery module includes: a bracket having a preset height direction; the vertical mounting posture is the posture in which the battery module is assembled and fixed to the energy storage device along the height direction; the horizontal mounting posture is the posture in which the battery module is assembled and fixed to the energy storage device along a direction perpendicular to the height direction; at least one battery cell disposed on the bracket; and at least two sets of connecting parts disposed in different areas of the bracket. Each set of connecting parts is configured to be adapted to one type of energy storage device. One set of connecting parts is configured to be adapted to the energy storage device adapted to the vertical mounting posture, and the other set of connecting parts is configured to be adapted to the energy storage device adapted to the horizontal mounting posture, so that the battery module can be installed on the corresponding type of energy storage device in the corresponding mounting posture through any set of connecting parts.

[0009] The battery module provided by this invention features multiple sets of connecting parts on a support frame. Each set of connecting parts corresponds to a connection interface on a specific type of energy storage device. This allows the same battery module to be compatible with various energy storage device models by selecting the appropriate set of connecting parts based on the device model. When assembling different energy storage device models, the production line does not need to replace the battery module; it only needs to select and use the set of connecting parts corresponding to that model for installation and fixation. This enables the sharing of battery modules across multiple project models, eliminating the need to design and manufacture separate battery modules for different energy storage device models. This significantly reduces the number of molds required for battery module structural components, lowering mold manufacturing costs. Furthermore, it standardizes the material specifications of the battery modules, reducing the types of materials used and lowering the management costs of material procurement, warehousing, and manual assembly.

[0010] In the above technical solution, optionally, each group of connecting parts includes a set of mounting structures, the mounting structures include multiple mounting holes or mounting bosses, and the mounting structures of different groups of connecting parts are different in at least one of the hole distribution, spacing or external dimensions.

[0011] In this technical solution, by differentiating the hole distribution, spacing, or external dimensions of the mounting structures of different sets of connection parts, each set of mounting structures can be precisely matched with the connection structure of only one type of energy storage device. This ensures the accuracy and uniqueness of the battery module assembly with the corresponding type of energy storage device through different sets of connection parts, thereby improving the compatibility and connection stability of the battery module assembly with different types of energy storage devices.

[0012] In the above technical solution, optionally, the bracket includes a bottom wall and a plurality of side walls surrounding the edge of the bottom wall, and each set of connecting parts includes at least two connectors, and the at least two connectors are respectively disposed on different wall surfaces of the bracket.

[0013] In this technical solution, at least two connectors in each set of connecting parts are respectively set on different wall surfaces. The different wall surfaces can be a combination of bottom wall and side wall, that is, at least two connectors are respectively set on bottom wall and side wall, or a combination of different side walls, that is, at least two connectors are respectively set on different side walls, so that the battery module and the energy storage device can be connected from at least two directions, thereby improving the structural stability of the battery module and the energy storage device after assembly and avoiding problems such as shaking and displacement of the battery module in the energy storage device.

[0014] In the above technical solution, optionally, the connecting part includes: a first connecting member disposed on the bottom wall; and a second connecting member disposed on at least one side wall.

[0015] In this technical solution, a first connector and a second connector are respectively provided on the bottom wall and side wall of the support to form a set of connecting parts. This type of connecting part is more suitable for energy storage devices that are installed and fixed from the bottom and side.

[0016] Optionally, in the above technical solution, both the first connector and the second connector are provided with a first mounting hole, and the battery module is connected to the corresponding energy storage device through the first mounting hole; wherein, the axial direction of the first mounting hole is set along the height direction.

[0017] In this technical solution, the axial direction of the first mounting holes on the first connector and the second connector is set along the height direction of the bracket, which is suitable for energy storage devices in which battery modules are assembled in a vertical mounting posture along the height direction of the bracket.

[0018] In the above technical solution, optionally, the multiple sidewalls include a first sidewall, a second sidewall, and a third sidewall, and the connecting part includes: a third connecting member disposed on the first sidewall; a fourth connecting member disposed on the second sidewall; and a fifth connecting member disposed on the third sidewall.

[0019] In this technical solution, based on the differences in the internal component layout of different models of energy storage equipment, such as the installation position requirements of components like the inverter support frame, front shell, and rear shell in the energy storage equipment, a third connector, a fourth connector, and a fifth connector are respectively set on different side walls of the bracket to form one set of connection parts, so as to accurately match the connection requirements of the internal components and shell of different energy storage equipment.

[0020] In the above technical solution, optionally, the third connector, the fourth connector and the fifth connector are all provided with second mounting holes, and the battery module is connected to the corresponding energy storage device through the second mounting holes; wherein, the axial direction of the second mounting hole is arranged perpendicular to the height direction.

[0021] In this technical solution, second mounting holes are provided on different side walls of the bracket to accommodate energy storage devices assembled from the side walls of the battery module. The axial direction of the second mounting holes is perpendicular to the height direction of the bracket. This method is suitable for assembling the battery module into the energy storage device in a horizontal, flat manner, as well as for scenarios where the outer shell and internal frame of the energy storage device need to be connected and fixed to the side walls of the battery module.

[0022] In the above technical solution, the connector may optionally include one of a threaded connector, a snap-fit ​​structure, or a plug-in connector.

[0023] Optionally, in the above technical solution, the connector and the bracket are an integrated structure.

[0024] In this technical solution, the integrated molding design of the connector and the bracket improves the structural strength of the connector and avoids the problem of the connector becoming loose or falling off during assembly and use.

[0025] In the above technical solution, optionally, the bracket includes: a first bracket; a second bracket, mounted on the first bracket, and the first bracket and the second bracket together form a receiving cavity, in which at least one battery cell is installed; wherein, the bracket is an insulating bracket.

[0026] In this technical solution, the battery cell is installed within the housing cavity of the bracket, which provides comprehensive protection for the cell, preventing it from being subjected to external impacts or compression. The bracket is made of insulating material, effectively preventing the battery cell from contacting the metal casing or other metal components of the energy storage device, thus preventing electrical short circuits and other accidents.

[0027] In the above technical solution, optionally, the number of battery cells is multiple, and the battery module further includes: a conductive busbar, which is mounted on a bracket and electrically connected to multiple battery cells; a data acquisition board, which is mounted on the side of the conductive busbar away from the bracket; and a first insulating sheet, which is disposed on the side of the data acquisition board away from the conductive busbar.

[0028] In this technical solution, the acquisition board is used to monitor the status of the battery cells and collect the operating parameters such as voltage, current and temperature of each battery cell in real time. The first insulating sheet is used to protect the acquisition board and prevent it from being damaged.

[0029] The second aspect of this application provides an energy storage device, comprising: a housing with an accommodating space inside and a connection interface on the housing; a battery module provided in the first aspect of the technical solution, the battery module being disposed within the accommodating space; and a fastener passing through the connection interface and being securely connected to the connection portion.

[0030] The energy storage device provided by the present invention has a connection interface on its housing, and fasteners pass through the connection interface and are fastened to the connection part to install the battery module on the energy storage device.

[0031] Since the energy storage device in this technical solution includes the battery module provided in the first aspect of the technical solution, it also has all the beneficial effects of the battery module provided in the first aspect of the technical solution, which will not be elaborated here.

Detailed Implementation

[0047] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0049] The following reference Figures 1 to 12 This invention describes a battery module and energy storage device proposed according to some embodiments of the present invention.

[0050] According to an embodiment of the first aspect of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 11As shown, the present invention provides a battery module 1 for installation in at least two different mounting postures on various types of energy storage devices 2. The mounting postures include a vertical mounting posture and a horizontal mounting posture. The battery module 1 includes: a bracket 10 having a preset height direction; the vertical mounting posture is the posture in which the battery module 1 is assembled and fixed to the energy storage device 2 along the height direction; the horizontal mounting posture is the posture in which the battery module 1 is assembled and fixed to the energy storage device 2 along a direction perpendicular to the height direction; at least one battery cell 11 disposed on the bracket 10; and at least two sets of connecting portions 12, which are respectively disposed in different areas of the bracket 10. Each set of connecting portions 12 is configured to be adapted to one type of energy storage device 2. One set of connecting portions 12 is configured to be adapted to the energy storage device 2 adapted to the vertical mounting posture, and the other set of connecting portions 12 is configured to be adapted to the energy storage device 2 adapted to the horizontal mounting posture, so that the battery module 1 can be installed on the corresponding type of energy storage device 2 in the corresponding mounting posture through any set of connecting portions 12.

[0051] The battery module 1 provided by this invention includes a bracket 10, at least one battery cell 11, and at least two sets of connecting parts 12. The battery cell 11, as the core of the battery module 1's power output, is fixedly mounted on the bracket 10 to provide power to the energy storage device 2. The battery module 1 can be installed in the energy storage device 2 in a vertical or horizontal mounting configuration. Specifically, the bracket 10 has a preset height direction as shown in the figure. Figure 1 , Figure 5 and Figure 6 The direction pointed to by the middle arrow A, such as Figure 6 As shown, the vertical installation posture refers to the battery module 1 being assembled into the energy storage device 2 along the height direction, that is, the battery module 1 being placed vertically into the housing space 208 of the energy storage device 2, so that the height direction of the battery module 1 is in the same direction as the height direction of the entire energy storage device. This ensures that the battery module 1 does not occupy too much horizontal space of the energy storage device 2, significantly reducing the footprint of the entire energy storage device 2. Figure 9As shown, the horizontal installation posture refers to the battery module 1 being assembled into the energy storage device 2 in a horizontal, flat position, with the height direction of the battery module 1 perpendicular to the overall height direction of the energy storage device 2. This reduces the overall height of the energy storage device 2 and lowers its center of gravity, improving its stability. Of course, the battery module 1 can also have other installation postures, such as being assembled into the energy storage device 2 at an angle along its height. The connecting part 12 is the assembly structure between the battery module 1 and the energy storage device 2. There are at least two sets of connecting parts 12, and each set of connecting parts 12 can have multiple connectors 121 to adapt to different installation positions of one type of energy storage device 2. Each set of connecting parts 12 corresponds to a connection interface 201 on a certain type of energy storage device 2. One set of connecting parts 12 can be adapted to the connection interface 201 of the energy storage device 2 when the battery module 1 is placed vertically in the energy storage device 2, and the other set of connecting parts 12 can be adapted to the connection interface 201 of the energy storage device 2 when the battery module 1 is placed horizontally in the energy storage device 2. Of course, multiple sets of connecting parts can include not only the two sets of connecting parts mentioned above, but also some other connecting parts, so that the same battery module 1 can be installed and fixed according to the model of the energy storage device 2 by selecting the corresponding set of connecting parts 12, so that one battery module 1 can be adapted to multiple different models of energy storage devices 2. In this way, when assembling different models of energy storage devices 2, the production line does not need to replace the battery module 1. It only needs to select and use the set of connecting parts 12 corresponding to this model of energy storage device 2 for installation and fixation. This enables the battery module 1 to be shared across multiple models of projects. It eliminates the need to design and manufacture corresponding battery modules 1 separately for different models of energy storage devices 2, which significantly reduces the number of molds to be developed for the structural components of the battery module 1 and lowers the mold manufacturing cost. At the same time, it standardizes the material specifications of the battery module 1, reduces the types of materials for the battery module 1, and lowers the management costs of material procurement, warehousing, and manual assembly.

[0052] Optionally, the various models of energy storage devices 2 may differ in at least one of the following aspects: the appearance of the housing 20, the internal structure, the internal structural layout, and the function. Of course, the different models of energy storage devices 2 are not limited to these, and will not be listed here.

[0053] In some embodiments, each group of connecting portions 12 may optionally include a set of mounting structures 129, the mounting structures 129 including a plurality of mounting holes or mounting bosses, and the mounting structures 129 of different groups of connecting portions 12 may differ in at least one of the hole distribution, spacing or external dimensions.

[0054] In these embodiments, each group of connecting parts 12 has a set of mounting structures 129. A set of mounting structures 129 can be multiple mounting holes or multiple mounting bosses, which are disposed at different positions on the bracket 10. The mounting structures 129 of different groups of connecting parts 12 differ in at least one of the following: hole distribution, spacing, or overall dimensions. Specifically, the hole distribution refers to the different positions of the mounting holes in each set of mounting structures 129. For example, in the first set of mounting structures 129, mounting holes one and two are respectively located at positions A and B; in the second set of mounting structures 129, mounting holes three and four are respectively located at positions C and D, or at positions A and C. The hole distributions in these two sets of mounting structures 129 are different. The spacing can refer to the different distances between multiple mounting bosses in each group of mounting structures 129. For example, the distance between mounting boss one and mounting boss two in the first group of mounting structures 129 is 30 cm, and the distance between mounting boss three and mounting boss four in the second group of mounting structures 129 is 27 cm. The distances between the mounting bosses in these two groups of mounting structures 129 are different. The external dimensions can refer to the different shapes of the mounting bosses in each group of mounting structures 129. For example, the shape of multiple mounting bosses in the first group of mounting structures 129 is triangular, and the shape of multiple mounting bosses in the second group of mounting structures 129 is square. By differentiating the hole distribution, spacing, or external dimensions of the mounting structures 129 of different groups of connecting parts 12, each group of mounting structures 129 can be precisely matched with the connection structure of only one type of energy storage device 2. This ensures the accuracy and uniqueness of the assembly of the battery module 1 with the corresponding type of energy storage device 2 through different groups of connecting parts 12, thereby improving the adaptability and connection stability of the battery module 1 when assembled with different types of energy storage devices 2.

[0055] In some embodiments, the bracket 10 may optionally include a bottom wall 101 and a plurality of side walls 102 surrounding the edge of the bottom wall, and each set of connecting portions 12 includes at least two connectors 121, which are respectively disposed on different wall surfaces of the bracket 10.

[0056] In these embodiments, at least two connectors 121 in each set of connecting parts 12 are respectively disposed on different wall surfaces. The different wall surfaces can be a combination of bottom wall 101 and side wall 102, that is, at least two connectors 121 are respectively disposed on bottom wall 101 and side wall 102. Alternatively, there can be a combination of different side walls 102, that is, at least two connectors 121 are respectively disposed on different side walls 102. This allows the battery module 1 and the energy storage device 2 to be connected and fixed from at least two directions, thereby improving the structural stability of the battery module 1 and the energy storage device 2 after assembly and avoiding problems such as shaking or displacement of the battery module 1 within the energy storage device 2.

[0057] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, the connecting part 12 includes: a first connecting member 122 disposed on the bottom wall 101; and a second connecting member 123 disposed on at least one side wall 102.

[0058] In these embodiments, a first connector 122 and a second connector 123 are respectively provided on the bottom wall 101 and side wall 102 of the support 10 to form a set of connecting parts 12. This type of connecting part 12 is suitable for energy storage devices 2 that are installed and fixed from the bottom and side, for example, such as... Figure 6 As shown, the battery module 1 is inserted into the accommodating space 208 of the energy storage device 2 from top to bottom through the opening of the front cover assembly 203 (lower housing) in a vertical mounting posture. Then, the upper cover 202 is fastened to the front cover assembly 203 (lower housing) along the height direction of the bracket. That is, the battery module 1 is assembled into the energy storage device 2 in a vertical mounting posture. The housing 20 of the energy storage device 2 is a housing 20 that is fastened and installed along the height direction of the battery module 1.

[0059] Optionally, there are multiple first connectors 122 and multiple second connectors 123, with multiple first connectors 122 disposed at different positions on the bottom wall 101 and multiple second connectors 123 disposed at different positions on the side wall 102.

[0060] In some embodiments, optionally, the first connector 122 and the second connector 123 are both provided with a first mounting hole 127, and the battery module 1 is connected to the energy storage device 2 of the corresponding model through the first mounting hole 127; wherein, the axial direction of the first mounting hole 127 is arranged along the height direction.

[0061] In these embodiments, the axial direction of the first mounting holes 127 on the first connector 122 and the second connector 123 is set along the height direction of the bracket 10, which is suitable for energy storage devices 2 in which the battery module 1 is assembled in a vertical mounting posture along the height direction of the bracket 10.

[0062] Optionally, the first mounting hole 127 on the first connector 122 and the first mounting hole 127 on the second connector 123 together form a mounting structure 129.

[0063] In some embodiments, optionally, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the multiple sidewalls 102 include a first sidewall 103, a second sidewall 104 and a third sidewall 105, and the connecting part 12 includes: a third connecting member 124, disposed on the first sidewall 103; a fourth connecting member 125, disposed on the second sidewall 104; and a fifth connecting member 126, disposed on the third sidewall 105.

[0064] In these embodiments, based on the differences in the internal component layout of different models of energy storage devices 2, such as the installation position requirements of components like the inverter support frame 27, the front shell 204, and the rear shell 205 in the energy storage device 2, a third connector 124, a fourth connector 125, and a fifth connector 126 are respectively provided on different side walls 102 of the bracket 10 to form one set of connection parts 12, so as to accurately match the connection requirements of the internal components and the shell of different energy storage devices 2.

[0065] Optionally, such as Figure 4 and Figure 5 As shown, there are multiple third connectors 124, fourth connectors 125 and fifth connectors 126. Multiple third connectors 124 are disposed at different positions on the first sidewall 103, multiple fourth connectors 125 are disposed at different positions on the second sidewall 104, and multiple fifth connectors 126 are disposed at different positions on the third sidewall 105.

[0066] Optionally, the first connector 122, the second connector 123, the third connector 124, the fourth connector 125, and the fifth connector 126 can be arbitrarily combined to form the connecting part 12 to adapt to the assembly requirements of different types of energy storage devices 2. For example, the first connector 122 and the third connector 124 form a connecting part 12, the first connector 122, the fourth connector 125, and the fifth connector 126 form a connecting part 12, and so on.

[0067] In some embodiments, optionally, such as Figure 3 , Figure 4 and Figure 5 As shown, the third connector 124, the fourth connector 125 and the fifth connector 126 are all provided with second mounting holes 128, and the battery module 1 is connected to the energy storage device 2 of the corresponding model through the second mounting holes 128; wherein, the axial direction of the second mounting hole 128 is arranged perpendicular to the height direction.

[0068] In these embodiments, second mounting holes 128 are provided on different side walls 102 of the bracket 10 to accommodate the energy storage device 2 assembled from the side. The axial direction of the second mounting holes 128 is perpendicular to the height direction of the bracket 10. This method is suitable for assembling the battery module 1 into the energy storage device 2 in a horizontal and flat manner, and for scenarios where the outer shell and internal frame of the energy storage device 2 need to be connected and fixed to the side wall 102 of the battery module 1.

[0069] Optionally, the second mounting holes 128 on the third connector 124, the fourth connector 125 and the fifth connector 126 together form a mounting structure 129.

[0070] Optionally, such as Figure 4 and Figure 5As shown, the first sidewall 103 and the third sidewall 105 are arranged opposite to each other.

[0071] In some embodiments, the connector 121 may optionally include one of a threaded connector, a snap-fit ​​structure, or a plug-in connector.

[0072] In some embodiments, the connector 121 and the bracket 10 are optionally integrated.

[0073] In these embodiments, the integral molding design of the connector 121 and the bracket 10 improves the structural strength of the connector 121 and avoids the problem of the connector 121 becoming loose or falling off during assembly and use.

[0074] Alternatively, the connector 121 may be mounted on the bracket by stamping, injection molding or welding.

[0075] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the bracket 10 includes: a first bracket 106; a second bracket 107, which is mounted on the first bracket 106, and the first bracket 106 and the second bracket 107 form a receiving cavity 108, in which at least one battery cell 11 is installed; wherein, the bracket 10 is an insulating bracket.

[0076] In these embodiments, by installing the battery cell 11 within the receiving cavity 108 of the bracket 10, the receiving cavity 108 provides all-around protection for the battery cell 11, preventing it from being subjected to external impacts or compression. The bracket 10 is made of insulating material, effectively preventing the battery cell 11 from contacting the metal casing or other metal components of the energy storage device 2, thus preventing electrical short circuits and other accidents.

[0077] In some embodiments, optionally, such as Figure 1 As shown, there are multiple battery cells 11. The battery module 1 also includes: a conductive busbar 13, which is mounted on the bracket 10 and electrically connected to the multiple battery cells 11; a data acquisition board 14, which is mounted on the side of the conductive busbar 13 away from the bracket 10; and a first insulating sheet 15, which is disposed on the side of the data acquisition board 14 away from the conductive busbar 13.

[0078] In these embodiments, the battery module 1 contains multiple battery cells 11, which are arranged in a preset series-parallel configuration within the receiving cavity 108 of the support 10. The battery module 1 also includes a conductive busbar 13, a data acquisition board 14, and a first insulating sheet 15. The conductive busbar 13 is installed at a preset position on the support 10 and is electrically connected to the electrodes of the multiple battery cells 11, achieving series-parallel electrical connection of the multiple battery cells 11. The data acquisition board 14 is installed on the side of the conductive busbar 13 away from the support 10.

[0088] The following describes a specific embodiment of the battery module 1 and the energy storage device 2.

[0089] In related technologies, when designing the structure of energy storage power supplies, the battery module structure is generally designed with upper and lower brackets, aluminum busbars, and other materials. The upper and lower brackets are assembled first, and the aluminum busbars are welded to form a module. When designing a new model, a new module is usually designed according to the stacking of components inside the new casing.

[0090] This solution utilizes additional fixing points (connectors 121) on each side of the upper bracket (first bracket 106) and lower bracket (second bracket 107) to enable a single battery module 1 to accommodate different casing models. This allows for modularization of the battery module 1, sharing of materials, and savings in structural component mold costs and material management costs. For example, if two different casings share a module, at least three sets of molds and material management costs for the aluminum busbar and upper and lower brackets are saved. If three different casings share a module, at least six sets of molds and material management costs are saved, and so on.

[0091] This invention features modular design, enabling multiple projects to share a single module through structural innovation, thus solving the problems mentioned in the background. The specific technical solution is as follows:

[0092] Adding fixing positions on each side of the upper and lower brackets allows for the sharing of modules among three or more machine models.

[0093] In the first model, both the fixing position 1 (first connector 122) and the fixing position 2 (second connector 123) of the battery module are used to fix the battery module 1 and the front cover assembly 203.

[0094] In the second model, the fixing position 3 (third connector 124) of the battery module 1 fixes the battery module 1 and the inverter support frame 27, the fixing position 4 (fourth connector 125) fixes the battery module 1 and the front shell 204, and the fixing position 5 (fifth connector 126) fixes the battery module 1, the front shell 204 and the rear shell 205.

[0095] In the third model, the fixing position 3 of the battery module 1 fixes the battery module 1 and the inverter support frame 27, the fixing position 4 fixes the battery module 1 and the front shell assembly, and the fixing position 5 fixes the battery module 1, the front shell assembly and the rear shell 205.

[0096] Implementation method: Add fixing positions on each side of the upper and lower brackets to modularize the assembled battery module 1, allowing different fixing positions to be assembled onto the casings of three or more different models.

[0097] This technical solution has the following significant beneficial effects:

[0098] This allows a single battery module 1 to meet the needs of different casing models, thus enabling modularization of the module and sharing of materials within the module, thereby saving on mold costs and material management costs.
